| description | The title molecule, C20H26O4, commonly known as meso-dihydroguaiaretic acid, is a naturally occurring lignan extracted from Larrea tridentata and other plants. The molecule has a noncrystallographic inversion center situated at the midpoint of the central C—C bond, generating the meso stereoisomer. The central C—C—C—C alkyl chain displays an all-trans conformation, allowing an almost parallel arrangement of the benzene rings, which make a dihedral angle of 5.0 (3)°. Both hydroxy groups form weak O—H...O—H chains of hydrogen bonds along [100]. The resulting supramolecular structure is an undulating plane parallel to (010). |
